Energy & Green Tech Sat, 06 Jun 2015 05:10:01 EDTnews352785404Innovative hybrid-electric powertrain for road sweepersEmpa, ETH Zürich and the road sweeper manufacturer Bucher Municipal have jointly developed a pioneering hybrid-electric powertrain for road sweepers in a CTI project. The concept is based on a gas-driven engine, which provides power to the electric motors. Compared to conventional sweepers, the energy consumption has been halved and CO2 emissions reduced by more than 60 percent. Bucher Municipal is currently working on a concept study to investigate possible commercialisation of the new technologies.http://phys.org/news/2015-06-hybrid-electric-powertrain-road-sweepers.html

That is the case with small size concentrated solar power, or CSP. It is a relatively new technology compared to the more mature photovoltaic technology, which is a "big boy, well grown and muscular" in the words of Francesco Orioli, Director at Soltigua, located near Cesena, Italy. His company produces energy generation systems capable of concentrating solar power. The company is also a partner in BRICKER, a project supported by the EU, which aims at reducing energy consumption of existing public buildings, using cutting-edge technology. In this interview with BRICKER, Orioli explains the challenges ahead for implementing prototypes of these new types of solar collectors in showcase sites in Aydin, Turkey and in Cáceres, Spain.http://phys.org/news/2015-03-solar-collectors-key-power.html

The associated IRENE research project is now being replaced by IREN2. The initial project focused on building a smart grid in the municipality of Wildpoldsried in the Allgäu region of Germany. The project partners are now using the grid to examine ways to stabilize the electricity supply using intelligent sub-units that operate with a decentralized electricity generation system. Specialists are also looking at ways to combine several small power generation units, and possibly battery storage devices as well, in a manner that would enable them to contribute to system stability in much the same way conventional power plants do. Wildpoldsried sometimes produces more energy than it needs because many of its residents operate solar power units, windmills, and biogas power generation systems, or cogeneration systems. The municipality's power supply voltage is controlled by variable local grid transformers, distributed power generation units and storage devices.http://phys.org/news/2014-11-energy-transition-phase.html
